When the people of Yemen came, ‘Umar started asking people in the group, Is there anyone among you from Qaran, until he came to [the tribe of Qaran] and said: Who are you? They said: Qaran. Umar’s reins - or Uwais`s reins - fell and one of them picked them up and gave them to the other. ‘Umar recognized him and said: What is your name? He said: I am Uwais, [ʼUmar] said: Do you have a mother? [Uwais] said: Yes. [ʻUmar] said: Did you have any whiteness [leprosy]? He said: Yes, but I prayed to Allah, may He be glorified and exalted, and He took it away, except for an area the size of a dirham near my navel, so that I would remember my Lord. ‘Umar said to him: Pray for forgiveness for me. He said: Rather you should pray for forgiveness for me; you are the Companion of the Messenger of Allah (ﷺ). ʼUmar (e.) said: I heard the Messenger of Allah (ﷺ) say: `The best of the Tabi`een will be a man called Uwais who has a mother, and he has some whiteness, then he prayed to Allah, may He be glorified and exalted, and He took it away, except for an area the size of a dirham near his navel.” So he prayed for forgiveness for him, then he disappeared in a group of people and no one knew where he ended up. Then he (Uwais) came to Koofah. We used to gather in a circle, remembering Allah, and he would sit with us, and when he spoke of Allah, his words would have an impact on us like that of no one else. And he quoted the hadeeth...

It was narrated from Qais or Ibn Qais, a man from Ju`fi, from `Umar bin al-Khattab and he mentioned a Hadeeth similar to that of Affan.
